This Solar Calculator will compute the size and estimated cost to install a solar energy system for your home or building. The solar calculator's financial analysis is based on energy bill savings you can expect and the net solar system cost, after tax credits and other incentives are applied. The solar calculator results are based on many assumptions and the limited data you will enter. An actual site assessment by a trained professional contractor will be needed to determine the actual costs and benefits of installing a solar energy system.

The team was professional in their interactions with me and they did a good job of leaving everything neat and clean when they finished the job. They responded quickly to a minor problem I experienced and I am completely satisfied with the job they did.

ALTERIS RENEWABLES, INC.Wilton, CT 06897 installed a Water Heating system

15 milesfrom you

This was a refurbishing of a hot water solar heating system original to the 1978 home. When we bought the property in 2003, we did not know if the system even worked. Kosmo Solar inspected it in 2006 and clearly laid out options. We were having the roof redone (complete tear off), chimneys replaced and gutters installed, and also explored PV options but our best solution was to refurbish the SDHW system. Kosmo Solar did an excellent job, coordinating well with chimney crew and roof and gutter people. We are confident system works well, and have also signed up for annual maintenance to preserve our investment. Refurbishing of 28 yr old existing SDHW system, not new installation
